Do all Sun Servers come with switch-mode power supply?

I was posted this question by my customer and i was dumb founded. Can anyone help me on this? Thank you!

I'm not absolutely certain I understand the term "switch-mode".
If they are referring to a power supply that can auto-sense the input voltage, such as whether it can function with 115VAC versus 230VAC, then the answer is "maybe".
Recent workstation systems will have that.
Smaller server systems will have that.
Mid-sized servers may or may not have that.
An example: Sunfire V480's were auto-sensing, whereas the V490's require a nominal 200-240VAC.
Another example: the Ultra 5 and Ultra 10 workstations had power supplies that required you to slide a selector switch.
You are going to have to provide specific models, to get accurate answers.
Alternatively, just look it up in the Sun System Handbook.

  • HT1490 When my macbook is fully charged, does the charger switch the power supply off, or does it continue to 'charge'?

    When my macbook is fully charged, does the charger switch the power supply off, or does it continue to 'charge'?
    (If I leave my laptop to charge whilst I'm out and it reaches 'fully charged' but is still switched on, will this continue to 'charge' my laptop? Or will it destroy my batter over time?)

    When the charge cycle completes, the pilot light on the MagSafe connector changes from orange to green. At that point the battery will be kept in standby mode, and the computer will be kept running with electrical power from the charger.

  • CNA & "switch redundant power supply"

    Just configured trunking between these switches:
    2950T-48-SI
    3508G-XL
    3548-XL
    The traffic appears to be flowing correctly through both the default VLAN and also my additional VLAN.
    Now, ALL of the 2950 switches on my network display this message: "switch redundant power supply failed" when I connect to them using the Cisco Network Assistant.
    Seems like the error message must be related somehow to the VLAN configuration I did.
    In a nutshell, I configured all connected Gigabit ports this way:
    switchport mode trunk
    switchport trunk encapsulation dot1q
    I only configured SOME of my switches for the trunking and additional VLAN - must all of them be configured the say way, even if I don't anticipate needing the additional VLANS on those switches?
    Thanks, Susan

    Hi Susan,
    Do you have redundant power supplies connected to the 2950s?
    If not, you are probably running into a cosmetic bug, CSCee96721.
    We can confirm this by issuing a "show env" in the CLI.
    You should see something like this:
    "switch#sho env all
    FAN is OK
    Internal POWER supply is OK
    RPS is NOT present
    RPS is FAULTY"
    Note that the last line indicates that the RPS is faulty, even though the line above it indicates that no RPS is present.
    If that applies to you as well, then you are hitting this bug. CNA is polling the same information, which is why you are seeing "switch redundant power supply failed" in CNA.
    The fix is in 12.1(22)EA3 and later.
    HTH,
    Bobby

  • HP DV2025TU laptop start as soon as switch on power supply. XP SP3, BIOS : F.39, help required.

    My HP DV 2025 TU model laptop start automatically as soon as i switch on power supply from power adaptor (Note : as my battery is totally gone so always need to start from power supply with power adapter)
    OS : XP SP3

    Please help me by providing solution.

    Suspend has always been problematic under Linux. It seems to be hit or miss for the most part, but here are some things you can try:
    Use an LTS kernel, tuxonice, pm-utils, etc. See Suspend and Hibernate
    Try a different graphics driver
    Tweak the driver module parameters or build your own driver.
    Unfortunately I don't have experience with the radeon driver, so I can only give you ideas.

  • Do all iPod Touches come with a 1 yr warranty?

    I bought my iPod Touch from amazon 4 months ago. So does it have a warranty? I am having a screen problem all of a sudden on my iPod Touch. Would apple fix this for me for free? It just happened all of a sudden( no accidents or anything) My screen shakes like crazy when I try to scroll anywhere or zooming in by pinching it shakes like crazy. Then it goes away and comes back. Does my iPod come with a warranty and would apple repair my iPod for free? Thanks

    Ipods have a  1 year warranty.
    If Apple determines that you ipod is defective and it is withing the warranty period, then they will replace.
    Have you tried the basics from the manual?  Restart, reset, restore.

  • Interfacing LabVIEW with PS-325 power supply

    Hello guys, I have  a power  supply  from Stanford Research systems, PS-325. This power source  have  a comunication port with pc that requires a  KUSB-488B cable. I have installed  the  drivers necesary for this cable and  drivers  for  power    supply   from  NI site, but   doesn't work. I have  a dedicated  GUI  from Keithley with i have  tested  the cable and conection, and   all good but in LabVIEW  doesn't work. I have made   a simple   VI  to  set the voltage  to  power source and I'm getting   ERR (-10737807343). Can anyone  help me  with   this? maybe  somebody have a  VI  for  this  power  supply. Thank you!

    It doesn't require a controller from Keithley. That's a choice that you or someone else made and not exactly a good choice. If Keithley provides its version of VISA, you need to install that but also NI-VISA as primary. The actual gpib driver must come from Keithley. You probably need to enable tulip support as well. The controller and instrument have to be listed in MAX.

  • Help - nonworking 1st Gen iMac 20" with bulging caps (power supply)?

    I have a 1st Generation (Rev. A) iMac G5 that does not power on. I looked at the logic board, and all of the capcitators appear OK. None are bulging. Most have a "K" on them, some have the infamous "X."
    I took my iMac into the Apple Store Genius expecting to be covered under one of the iMac G5 extended repair programs for out of warranty iMac G5s:
    http://www.apple.com/support/imac/powersupply/repairextension/
    http://www.apple.com/support/imac/repairextensionprogram/
    I did not qualify for either, as the one is only for video AND power issues, and the other only for Rev. B iMacs.
    So I took my iMac home looking to buy a power supply. I took the power supply out and opened it up and found all "X" capacitors, some of them bulging.
    So what is my next step?
    • Should I phone Apple Customer Relations at 800-767-2775 or Executive Relations 800-275-2237?
    • Should I take the power supply back in and show this to the Apple Genius and explain my situation?
    • What about the logic board? Should I demand Apple replace that too, since it has the X caps?
    I am out of warranty and no AppleCare. But according to other threads, like this one, this is a known issue and Apple should replace both my logic board and my power supply. But the genius I dealt with this morning seemed very knowledgeable and said he has been working on Macs for 20 years. He actually checked in my Macbook with a couple of issues and is resolving them no problem. But no joy on fixing the iMac.

    I took my Macbook in yesterday for video flicker and misbehaving battery. Received new battery, logic board, and inverter cable in about 32 hours. Kudos to Apple for fixing my in-warranty machine so quickly and not blinking an eye. The Genius who checked in my MacBook asked if I read about these repairs on the web, as he said it is a major problem. Ironically, since then I have been cautioned twice by Apple about what I read on the web.
    What does that have to do with my iMac saga? Absolutely nothing, other than since I went to pick up the MacBook, I took the iMac back in. Plus, I am trying to find some words of praise with Apple's prompt, no-hassle repair as with this iMac issue I can find no words of praise.
    I started out with this new Genius tonight by explaining I brought in the iMac yesterday and the Genius didn't even open my iMac but just checked the serial number and EMC number and must have been confused on the programs. I told him he denied me either program and said the one issue was for Video AND Power issues, and since I did not have a video issue, I was denied. I was asked who helped me, and gave his name, and I could tell the genius in front of me regarded him highly.
    Anyway, they brought out the MacBook, I signed for it, put it back in my laptop bag. Attention turned back to the iMac, and I could just sense a reluctance to help me. I had mentioned that there were X capacitors on the logic board, but that none of them were bulging, and I had read that could be a problem in the future and that people were getting logic boards replaced even though the problem was with their power supply and the logic board appeared fine. I received the party line again about misinformation on the internet and not believing everything I read. At least I convinced this guy to open up my iMac, which he would not do in front of me but took it into a back room.
    He came back out and said my capacitors were fine and there was nothing he could do. (Well, I had already told him they were fine.) I said that this was for power issues and the problem is obviously with my power supply and he said he could not help me with that.
    I was/am very ticked off and just didn't feel like getting into it. Normally I would have asked for the manager. The genius wouldn't even look me in the eye. I feel like I have leprosy or something. Has anyone else with a Rev. A iMac with serial numbers for this program get denied? I have not read such a thing on this forum. Someone please post a link to comfort me so I know I am not the only one.
    I just left, in defeat. I've got enough Mac service centers around me that I am going to take it to one of them. In fact, I DID take it to one of them first on Monday morning, but didn't have the original receipt with me, so they said that could be an issue, so I just left and took it to the Apple Store since I was already out that way.
    Maybe tomorrow I will find comfort back in the arms of one of those hybrid computer stores. The saga continues...

  • 3750X stack with broken 715W power supply

    I have a stack of 2 WS-C3750X-48P      15.0(2)SE6            C3750E-IPBASEK9-M       
    Each switch has two 715W power supplies.

    Hi Charles, yes the 2 switches act like one stand alone sw
    Switch 1 connected to Switch 2
    and with the second cable,
    Switch 2 connected to Switch 1
    There are no stack power cables.

    I have only one electrical line to the rack
    The problem is that a broken power supply caused to switch off all the rack.
    In fact the master electrical switch of all the rack went down.
    Last 3 months the same problem  happened twice to two different stacks.
    Is it possible a firmware bug ?
    Tell me if you need further info. Thanks a lot

  • Fan noise when I Target Disk Mode - power supply or 500 GB drive, or RAM?

    I have a Revision B iMac G5 which falls squarely in the power supply replacement program and has had the power supply replaced twice. I'm wondering if my extra RAM, or larger hard drive could be to blame for the fan speeds upramping at random during normal operation, and always when I Target Disk Mode the machine. I have a Western Digital WDC WD5000KS-00MNB0
    and two 1 GB RAM modules with the following spec PC3200U-30330.
    Before I try to pin down the cause one by one, has anyone noticed whether there are 500 GB drives on these Macs which will not up the fan speeds? Has anyone noticed whether target disk mode on these models will not increase the fan speeds when RAM is upgraded to 2 GB?

    I have the same iMac as yours. Changed the original 80 gig hdd to a 250 gig. Both drives are seagate barracudas. I also upgraded the memory to 2gigs. The fan noise was terrible.
    6 months later a ram module gives up the ghost. I originally thought hard drive, so purchased a Western digital 500 gig WDC WD5000AACS-00ZUB0. (The green power series).

    Fans very quite. still waiting for the replacement ram module;
    to see if extra ram will increase fan noise

  • Mac Pro 2,1 Spontaneous Restart with No Boot - Power Supply PSU Problem?

    One day I was working away on my Mac Pro 2,1 Quad Core 3.0 (2007) with 8 gb ram running Lion and it just shut itself off like someone pulled the power cord (but no one did of course). Then it attempted to restart, but wouldn't boot. Basically I haven't been able to use it since as I can't get the computer to stay on for any length of time.
    I'm thinking its either the power supply or the, oh no, logic board.
    Symptoms have been like this so far:
    Initially I would get a chime and a boot start but then I would find the computer would shut itself off somewhere in the process and try to restart. Usually the next time I would get no chime and a horrible repeated clicking of my optical drive with a rythmic fan whirring up and down on the original ATI x1900 xt graphics card. I would have to manually power off with the power button to make it stop. Sometimes it would try to restart again anyway. The only way I could get a chime again was to unplug and wait (longer the better). But even if i got a chime and a start of a boot, invariably the computer would turn off again.
    I couldn't boot from another source, I couldn't run apple hardware test, I couldn't run diagnostic,... it just wouldn't stay on to do it.
    I hauled my mac pro (out of warranty) to the apple store genius bar and the problem presented itself, continuously. The gent was able to get fsck to work long enough to determine my hard drive was ok and said it was one of three things - the power supply, the graphics card, or the logic board. He said because the comp powered on and then shut off, and because there was intermittent chiming, he didn't think it was the power supply. He thought it was the graphics card and said I could leave my Mac for 10 days and they could take a looksy, or I could just install a new graphics card on my own.
    I chose the latter, bought a ATI Radeon 5770 from the apple online store for $275 and installed it.
    Problem persists.Exactly the same as before. Got initial chime, then next time no chime, optical drives clicking and graphics card fan whirring up and down rhythmically.
    I had a touch of time to disconnect everything and I get a chime consistently now when I have my boot drive, graphics card, 4 gb ram, and monitor attached. (As well as wireless mouse, keyboard, trackpad). I even got to logon once only to have a prompt shut off and restart attempt. also I verified it was at least one optical drive clicking (when I removed them both) during these boot attempts.
    The improvement in chiming seemed to be when I unseated one ram riser ( I have to with 2 x 2g ram modules each).
    I also checked the diagnostic leds on the logic board and all was as it should be... says I got trickle power and rail power etc.
    Is there anything else I can do to determine what's wrong? What do you guys think is wrong? Could it be bad RAM? Power Supply? Logic Board?
    All your help is massively appreciated in advance!

    Well I ran as many tests as I could with no definitive results to the point I would have to start buying replacement parts and testing that way. I opted to take it back to the apple store and they said it's (dun dun dun dunnnnn) the logic board.

  • Is airport  extreme working with 220 v  power supply?

    my cousin  gave me an airport extreme as present , bought in USA.Can I connect it with 220v power supply (greece) or what I must do to connect it to 220v power supply?

    It will accept AC input voltages between 100 and 240 AC,  50 to 60 HZ.  All you will need is an adapter plug to interface between the US plug and the Euro/Greece wall socket. These adapter plugs are low cost.

  • Do all macbook pros come with Time Machine?

    I have a friend with a new MacBook Pro, and I told him I would help him move his iTunes library from his old pc desktop, but now I don't think this is possible. Is it?
    I have lots of other questions about moving iTunes and sharing an iTunes account with your partner. HELP!

    This is the method to migrate iTunes from PC to Mac :

    The TM question isn't relevant, as it isn't found on PCs. However, it should be present on a new MBP (the software, that is - you still have to designate a drive for it).

  • Do all T430s models come with the nVidia 5300 chipset?

    We have a small inventory of T430s laptops, and only on some of them do I see the nVidia chipset listed in Device Manager, while all of them include the Intel HD 4000 chipset.
    Is there a specific SKU on the T430s that include the nVidia chipset?   And can the nVidia chipset be added to the T430 as an addon card, or does it come onboard the motherboard as part of the SKU only?
    Solved!
    Go to Solution.

    Some motherboards have the NVidia chip and others (most) do not. It is part of the motherboard and cannot be added later
